  A polymerization process to produce polyol polymer useful in the formulation of thermoset coatings, including the polymer so produced, is disclosed. The polymers are characterized as having at least one main chain and a plurality of side chains attached thereto. The polymerization process comprises combining in a solvent, at an elevated temperature and for a predetermined period of time, an addition-polymerizable monomer (that is also a free-radical initiator) together with an ethylenically-unsaturated monomer (having a nucleophilic or an electrophilic moiety), to initiate addition copolymerization of the addition-polymerizable monomer with the ethylenically-unsaturated monomer, whereby propagation of the reaction forms the main chain of the polymer. Meanwhile, also combined in the solvent is a polymerizable, carbonyl carbon-containing, ringed molecule -- such as a lactone -- which, at the elevated temperature, has a ring portion that opens to initiate ionic-copolymerization (of the now-opened ring molecule) with the nucleophilic-containing or electrophilic-containing moiety, whereby propagation of this reaction forms the side chains of the polyol polymer. Termination of the addition-copolymerization and ionic-copolymerization reactions is effected when the polyol polymer attains a predetermined number-average and/or weight-average molecular weight. The polymerization process is characterized in that each of the main-chain and side-chain propagations occurs substantially simultaneously, relative to the other, without using a catalyst.

  本发明公开了一种聚合工艺，用于生产热固性涂料配方中有用的多元醇聚合物，包括以这种方法生产的聚合物。聚合物的特点是至少有一条主链和连接在主链上的多条侧链。聚合工艺包括在溶剂中，在较高温度下和预定时间内，将可加成聚合单体（也是自由基引发剂）与乙烯基不饱和单体（具有亲核或亲电分子）结合在一起，引发可加成聚合单体与乙烯基不饱和单体的加成共聚，反应的扩展形成聚合物的主链。同时，溶剂中还含有可聚合的、含羰基碳的环状分子（如内酯），在升高的温度下，该分子的环状部分打开，从而（使现已打开的环状分子）与亲核或亲电分子发生离子聚合反应，该反应的扩散形成多元醇聚合物的侧链。当多元醇聚合物达到预定的数均分子量和/或重均分子量时，加成聚合反应和离子聚合反应即告结束。该聚合工艺的特点是，相对于主链和侧链而言，每个主链和侧链的扩展基本上是同时进行的，无需使用催化剂。

  The present invention provides for a process for producing an alkali-soluble graft polymer having at least one main chain and a plurality of side chains attached thereto, the process comprising the steps of: combining, in a solvent contained within an agitated reaction zone, (1) at least one vinylic monomer that is capable of forming free radicals, (2) at ;east pme ethylenically-unsaturated carboxylic acid monomer that is capable of addition-copolymerizing with the vinylic monomer in the presence of the thus-formed free radicals, and (3) cyclic ester molecules that are capable of ring-opening in the presence of the carboxylic acid monomer, thereby producing a reactant-initiatable polymerizable mixture; and subjecting the reactant-initiatable polymerizable mixture to a preselected temperature and pressure effective to cause the vinylic monomer and the ethylenically-unsaturated carboxylic acid monomer to free-radically addition-copolymerize to form the graft polymer one main chain and to cause the cyclic ester molecules to ring-open at the inner ester bonds thereof and to graft onto the polymer main chain, thereby forming the side chains of the graft polymer, the process being characterized in that the main-chain and side-chain formations of the graft polymer occur substantially simultaneously. The present invention also provides for graft polymer produced in accordance with the inventive process.
